Abstract: In this paper, the numerical simulation of the swirling turbulent flow of a polydisperse suspension in the hydrocyclone with an injector is carried out. The 2D axisymmetric approximation of Reynolds Stresses Model and model of mixture are used to describe the swirling turbulent flow field of suspension and particles parameters in the hydrocyclone. Special attention is paid to the clarification of mechanisms of injection influence on the reorganization of hydrodynamic fields and, finally, on classification mechanisms. It is shown that the tangential injection method more strongly affects the separation curve as compared to the radial method, which is consistent with the experimental data.

Keywords: hydrocyclone, injection, polydisperse suspension, computational fluid dynamics.
